Seating Company, Grand The present invention relates to chairs,particularly such as are used in theatres; and its ob ject is to providesuch a chair having an improved back and improved means for mounting theback on its support.

This and any other and more specific objectshereinafter appearing areattained by, and the invention finds preferable embodiment in, the chairconstruction particularly described in the body of this specificationand illustrated by the accompanying drawing, in which:

Figure 1 is a front view of the back of a theatre chair and of a portionof its supporting side standards, partially sectioned on a planecorresponding to line I-l of Figure 2;

Figure 2 is a sectional view (enlarged) of a portion of the same takenon line 2-2 of Figure 1;

Figure 3 is a fragmentary view (enlarged) of portions of the chairs backwith connecting and mounting means;

Figure 4 is a sectional line 44 of Figure 3;

Figure 5 is a view in perspective of a retaining element;

Figure 6 is a front view of the back of a theatre chair illustrating amodified construction;

Figure 7 is a sectional view (enlarged) of a portion of the same takenon line 1-1 of Figure 6; and

Figure 8 is a view in perspective of the modified retaining element usedin the form shown in Figures 6 and 7.

In the drawing is illustrated a theatre chair having a back I mounted onsupporting side standards 2 as by threaded means passing through theflanges 3 of these standards, a preferable form of such mounting meansbeing shown in Figures 3 and 4.

This chair back comprises a body or frame, the comparatively rigidforward and rearward sheet members 4, 5, of suitable material as plywood or the like, these members being fastened together in the relationshown by suitable means as the screws 6. An upholstery sheet 1 ofsuitable material, as textile fabric, leather or the like, extends infront of said forward member 4 with stuffing indicated at 8therebetween. The edge portion 9 of this sheet i is turned over theperipheral edge 10 of the forward member 4 and to the position shownwherein it is held or clamped between the frame members 4 and 5.

A rim I I of metal or the like extends around the peripheral edge l2 offrame member 5 and at I3 is turned over its front side and into heldengagement with the lugs [4 of the round flat retaining view thereoftaken on elements l5 seated in sockets IS in the front or inner side ofthe rearward member 5, these sockets and elements being adjacent theparallel peripheral edges of said members, all as illustrated in Figures1 and 2, one of said retaining elements being 5 shown in Figure 5.

In the slightly different construction illustrated in Figures 6, 7, and8, the retaining elements I5 are elongated and are fastened, as byscrews IT, on the rear or inner side of the forward member 4, 10 withthe edge portion 9 of the upholstery sheet 1 held therebetween. SocketsI6 in the rearward member 5 may be provided to receive these elements I5In this construction the edge l8 of the rim I I abuts against theprojecting outer end l9 of the elements I5 Inasmuch as the edge of theturned over portion I3 of the rim engages under the lugs I4 of the roundretaining elements I5 as shown in Figure 2 or under the projectingouterends l9 of the elongated retaining elements I5 as shown in Figure 7,these retaining elements hold the rim on the peripheral edge l2 of theframe member 5 thus dispensing with nails or the like. The rim in eitherconstruction is shown with a rear flange 20 engaging the rear side ofmember 5.

Preferable means shown in Figures 3 and 4 for mounting the chair back onthe standards 2 comprises a nut member 2| whose threaded shank 22extends into a bore 23 through frame member 5 0 and whose flat head 24has spurs 25 thrust into the inner or front side of said member. Thescrew 26 extends through the standards flange 3 and is turned into thisnut member to mount the chair back.

The invention being intended to be pointed out in the claims, is not tobe limited to or by details of construction of any embodiment thereofillustrated by the drawing or hereinbefore described.

I claim:

1. In a chair back: comparatively rigid forward and rearward sheetmembers forming the frame of the back; retaining elements held betweensaid members adjacent the parallel edges thereof having forwardlyextending lugs; a rim extending around the edge of the rearward memberand turned over the front side thereof into engagement with the innerside of said elements; an upholstery sheet in front of the forwardmember having its edge portion turned over the edge thereof and betweensaid members means for fastening said members together with the edgeportion of the upholstery sheet clamped between them.

2. In a chair back: comparatively rigid forward and rearward sheetmembers forming the frame of the back; retaining elements held betweensaid members adjacent the parallel edges thereof having forwardlyextending lugs; a rim extending around the edge of the rearward memberand turned over the front side thereof into engagement with the innerside of said elements and having a flange engaging the rear side of therearward member; an upholstery sheet in front of the forward memberhaving its edge portion turned over the edge thereof and between saidmembers; means for fastening said members together with the edge portionof the upholstery sheet clamped between them.-

3. In a chair back: comparatively rigid forward and rearward sheetmembers forming the frame of the back one of said members having socketsin its inner side; retaining elements seated in the sockets havingforwardly extending lugs; a rim extending around the edge of therearward member and turned over the front side thereof into engagementwith the inner side of said elements; an upholstery sheet in front ofthe forward member having its edge portion turned over the edge thereofand between said members; means for fastening said members together withthe edge portion .of the upholstery sheet clamped between them.
